APPARATUS FOR HEATING FLAT-IRONS AND SIMILAR ARTICLES.

SPECIFICATION forming part of Letters Patent No. 246,026, dated August 23, 1881.

Application filed March 10, 1880.

To all whom it may concern Be it known that I, WILLIAM MQOARTY, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Apparatus for Heating Flat-Irons and Similar Articles, of which the following is a specification.

My improvements relate to contrivances for heating and holding while heating by the flame of a lamp flat-irons and similar articles; and they consistin a skeleton or holder having somewhat the contour of a large chimney with openings in the sides for receiving the articles to be heated, and which is completed by the insertion of such articles, and which is specially constructed and adapted, both to heating and as to combustion, as herein set forth; and also in the construction and combination of an improved form of cone or'dome for lamp-burner with the skeleton-holder in such a manner as to enable the skeleton to perform the functions of holder, of chimney, and of burner for the lamp to a certain extent, and to dispense with the dome, ordinarily made a part of the lampburner, of whatever construction, as hereinafter described.

Heretofore many devices have been constructed in the effort to perfect a heater for flat-irons to be heated by flame and fiat-irons adapted for heating by such apparatus, some of which I have myself invented and have obtained patents for, the object sought in these devices more or less directly being to secure quick, clean, and high heating of the iron, to obviate the difficulty of rapid cooling of the irons after they are heated, and to secure for the heating of them an apparatus at once convenient, efi'ective, and reliable, the operation of which shall be free from smokiness and danger of explosion, and to secure the protection of the operating parts of the irons heated from dirtiness.

My improvements, so far as they relate to flat irons, flut-ing -irons, 850., adapted to be heated by the apparatus herein described, have been set forth in other applications now in the Patent Office, and are only referred to herein so far as may be necessary to describe the ap- (ModeL) paratus for heating and the improved construction of the dome as a part thereof. Heretofore in all this class of apparatus for heatin g great difficulty has arisen in regard not only to the general construction of the holdingpart of the heater, but also with respect to the burners to be used with the lamps, it being desirable to bring the burner within or close to the flat-iron to be heated, so as to economize heat, and to construct a burner which shall give a complete combustion of gases formed from the wick and the oil it carries, to make as wide, clear, and full a flame as possible, and while retaining in it the best form to avoid the attendant difficulty of the melting or rapid destruction of the burner by the high degree of heat to which it is subjected if placed in the desired position. It is to obviate these and other difficulties and to attain greater perfec- .tion in this class of apparatus that I have conducted experiments leading to the perfection of my present improvements, the nature of which will be understood from the following description and by reference to the accompanying drawings, in which- Figure 1 shows a contrivance embodying my improvements in one form in perspective--that is, it shows a lamp of large size and of two burners, having an oil-tank in the bottom and a water-tank above it for safety, and on one of the burners is fixed. an improved skeleton holder with a segment of fluting-iron thereon, and on the other burner is shown my improved dome. Fig. 2 shows, in elevation, a lamp in which appears in section in a plane ofits shortest diameters my improved device, with flatiron and fluting-iron in position therein. Fig. 3shows the same skeleton-holder, in elevation, seen at right angles to the plane of its longest diameters,with afiuting-iron in place therein.

Fig. 4 shows, in elevation, my improved dome in its separate form, or as adapted to be used on alamp-burner apart from the skeleton. Fig. 5 shows, in a section on the plane of its longest diameters, the bottom part of the skeleton holder,with the dome constructed therein. Fig. 6 shows,in top-plan view, a lamp on one burner of which appears my improved dome, and on the other burner the dome as it is adapted to be used with the holder shown in Fig. 5. Fig. 7 shows, in perspective, my improved flat-iron, Fig. 8 shows, in top plan, the bottom part of theflat-iron. Fig. 9 shows the taker, by which the bottom part of the flat-iron is handled. Fig. 10 shows a section of the flat-iron on a vertical plane passing through its center. Fig. 11 shows, in bottom-plan view, a flitting-iron adapted to be used with my holding device in place of the bottom part, B, of the device shown in Fig. 7.

A is ahandle-plate, having a circumferential lip,'lc 7t, and within it a horn, l.

B is the base part of my flat-iron, having a rabbet, g g, which the lip 7c fits.

e is a slot, into which 19 takes; and m is an inclined slot, into which the horn l takes.

D is a handle holding the spline or small metallic rod q, adapted for insertion in the diagonal slot h in the side of the base B, and by which it is handled when the plate A is 011' from it.

E is a base-plate, constructed like the base B, to which is fastened a corrugated flutingiron, O, by means of screws through the lugs Kis the body ofthelamp; andWis theburner, made large and strong, of any approved pattern, but perforated to admit of draft, and having a strong ledge for a chimney-carrier.

Q is a skeleton holder or apparatus for holding irons, constructed of metal, preferably cast-iron. It is constructed at its bottom part, 3 of a circular form in cross-section, and has a bottom or base end adapted to be placed on and held in the ledge of the burner W, just as a large lamp-chimney would be placed and held. The skeleton Q may be somewhat contracted above the bottom, as at 2, on the exterior, and must be so contracted on the interior. It is then enlarged on either side, as at S S, and, is contracted toward the top from S S, as shown in Figs. 1 and 3.

u is an opening in the flattened side of the skeleton-holder, having the top 7t" of the same general form as the lip on the han'dleplate A, and constructed to receive and hold the iron B or E in the rabbet g, as shown in Fig. 1.

t t are loops of metal, which may be placed so as to catch and hold the upper ends of the irons placed in the openings at a.

o is the upper end opening of the hollow skeleton Q 5 and X is the internal cavity in the skeleton Q, bounded by its walls and by the irons B E when in position, as shown in Fig. 2. The sides of the skeleton-holder Q, in which are the openings at, are not perpendicular, but slope inward toward the top for three reasons: first, because the cavityX should be constructed toward the top to secure the best draft; second, because the irons B E are heated better and quicker in the inclined position, since the flame and heated current from below impinge more directly on their heating-surfaces; and, third, because the iron, when placed with its rabbet g in the opening it, takes and holds its position more securely, and makes a closer joint with the edge It, so as to prevent the access of air as much as possible.

to is my improved dome for a lamp-burner,

and is both a part of the lamp and a part of the skeleton-heater Q, and may be made either in a separate piece of metal, as in Figs. 1, 4, and 6, or solid with the base part of the skeleton Q, as shown in Fig. 5, the latter form being the most economical and convenient way of making it. As made in a separatewform, (shown in Fig. 4,) it has a circular bottom part to fit the top or ledge of the burner, as in the ordinary construction of a dome. It has two flattened leaves rising on either side nearly parallel with each other, but approaching slightly toward the top, and of a width a little greater than the longest diameterofthe wick-tube of the burner. Each of these leaves has a lip bent over or projecting at the top inward for a slight distance, curved so as to present the edges of the lips nearer to each other in the middle, and receding by the curved lines toward the ends of the leaves, while the latter are cut away at the ends in lines of smaller curves, so that they are considerably farther apart below the lips, at the ends, than at the lips. The precise form of this improved dome w is somewhat difficult to describe in words, and has been worked out as the result of a large number of experiments into a shape readily understood from the drawings, 'as constructed to be used with a wicktube one and one-half inch in diameter one way at the top, and about one-eighth ofan inch in diameter the shortest way at the top. The circular bottom part of the dome is about two inches in diameter, and the leaves are about two inches longat the extreme length through the bottom of the slots between them at either end. The leaves reach about nine-sixteenths of an inch at the highest point above the top of the wick-tube of the burner when the dome is in place therein, and they approach at the top, with nearly straight parallel sides, to within seven-sixteenths of an inch of each other,while the lips project inward toward each other in the middle about three-sixteenths of an inch, and to within about one-fourth of an inch apart, the projection of the leaveslessening and the distance between the lips increasing by the gradual curve on either side toward either end of the leaf until at the extreme end the leaves are about three-eighths or seven-sixteenths of an inch apart, while the curved slot at the end extends to a depth below the leaves of nearly one-half inch. This formation of the dome I find to produce the most complete combustion and to give the least smokiness thereto, and also to produce the greatest amount of heat. This dome in its separate form may be struck up from sheet metal or may be cast, the in ternal form and the contour of the lips being an essential part, while the external part is comparatively immaterial. When combined and made in and solid with the skeleton Q, as shown in part in Fig. 5, the same internalform and the same relative proportions of the leaves and lips and slots or opening between are preserved as when constructed in the separate form; but the external part is blended with and modified by the casting of the base of the skeleton Q. It is more economical to make it in this Way, and in practice I find it more convenient and more desirable than when made in the separate form.

I claim as of my inVention- 1. The heater or skeleton-holder Q, consisting of a metallic shell widened at S S, on one or more sides containingthe openingu, adapted to receive the base part of the iron, and having the base y, and cavity X, and opening '0,
